With our patented Laser Ultrasonics technology we are able to understand the welding seam inspection inline in all welding processes. Through integrated and contactless measurements (that allow high-resolution measurements on the hot weld), the testing of the welding seam is completed within seconds after the welding has been done.
Metallic components are often coated dielectrically in order to optimize the operating characteristics (such as tribology).
With Terahertz technology (THz) such coatings can be measured efficiently inline.
3D printing / generative manufacturing / additive manufacturing
In recent years the rapid development and quality improvements in the field of 3D printing for plastic and metal components has enabled many applications, including the serial production of critical components. Using the OCT inspection technique (for plastics) or Laser-Ultrasonics Technology (LUS, for metals) allows to monitor the quality of the products directly during the printing process. This gives the possibility to intervene immediately to correct occurring faults inline.
The OCT (Optical Coherence Tomography) provides insight into nearly all common polymer materials used in the industrial environment. As a tomographic measurement technique, OCT delivers information about the internal structure in order to detect and characterise cracks, defects, inclusions, pores, etc. OCT not only controls the quality and functionality of the plastic products, but also delivers relevant information to help understand and optimize the manufacturing process.
Hidden (adhesive-) layers
With the Terahertz technology (THz) it is possible to look through relatively thick plastic layers and test hidden layers non-destructively (e.g. adhesive layers). The terahertz waves used are not harmful for health (no ionizing radiation), but still make it possible to look inside many optically non-transparent materials.
Carbon fiber reinforced plastics
Delaminations in CFRP materials are often a big problem as errors cannot be identified by inspection of the sample-surface. By using Laser Ultrasonics technology we are able to solve this problem in a non-destructive way!
Testing of hidden adhesive layers
The homogeneity of adhesive layers, which is not visible or accessible after the joining process of the components, should often be tested. The modern technique of Photoacoustic Imaging provides a solution in such cases. For example you can see here (b) errors in the adhesive layer between (a) a non-transparent plastic component and a metal component – and (c) the adhesive surface in a PAI-Scan.
Energy, resources, and raw material efficiency
Using process-integrated techniques from the NDT (Non-Destructive Testing) technologies portfolio means that errors can be identified at an early stage – saving time, energy, and cost.
With direct control of your processes, you can always operate them optimally without compromise. This results in a reduction of energy input, materials consumption, and process time. Through 100% quality control, only certified zero-defect products are delivered to the customers.
Dare to go to the limits within product and process design – through integrated process analytics and 100% quality control you save time and money, and it’s hassle-free. We can support you in these matters!
Embedded particles in lacquer coatings
In lacquer coating layers (or similar coatings), embedded particles (of different materials) are very important for the functionalization of the coating or for e.g. a perfect automotive-metallic-coating.
With the low-cost OCT method we are able to monitor and characterize the partial embedding, which helps to secure and optimize the production process.
